Definitions

  • intestinal stoma a surgical procedure which diverts intestinal transit outwards by exteriorizing an intestinal segment through the intestinal wall, thus avoiding the passage of bowel contents through the affected segment. This procedure is called “intestinal stoma” and can be performed either during emergency surgery or previously planned and scheduled.
  • intestinal stomata There are several ways to classify intestinal stomata. One of them is by referring to the level at which the intestinal transit is exteriorized. Therefore, an intestinal stoma that exteriorizes the large intestine (colon) is called “colostomy”, and one that exteriorizes the small intestine at any of its three sections—duodenum, jejunum and ileum—is called “duodenostomy”, “jejunostomy” or “ileostomy”, respectively. Under special circumstances, a stoma can be designed to divert the urinary tract in the same way as it diverts the stool, and this is called “ileal conduit”.
  • the fecal or urinary output exiting through a stoma is generally contained in a pouch-type disposable reservoir, which is adhered around the exteriorized intestinal mucosa and is changed after use.
  • a pouch-type disposable reservoir which is adhered around the exteriorized intestinal mucosa and is changed after use.
  • the design of a device for voluntarily regulating the outward flow of stool was developed with the purpose of improving the quality of life of these patients and reducing the high costs associated with said condition since, in many cases, intestinal reconnection is not possible, creating an “irreversible stoma” status.
  • the main objective is to provide voluntary constraint of intestinal transit of a stoma via a sphincter-type intestinal valve, which is surgically implanted when creating the intestinal stoma by applying minimal changes to the standard technique described in the literature, or else implanted during a second surgical event in patients with an existing stoma.
  • Said device can be mainly used in two different modes: as a stoma-regulating sphincter, which provides voluntary control for temporarily holding in the bowel contents, or as an electromagnetic valve in the absence of an intestinal stoma to contain intestinal transit to an intestinal segment specified by the surgeon to another damaged segment with specific therapeutic purposes and controlled by the patient using an external device.
  • the sphincter-type intestinal valve would significantly reduce the costs associated with this medical-surgical condition, not only for the patient but for the healthcare systems, improving the quality of life for millions of people. Furthermore, the electromagnetic intestinal valve would provide a valuable tool for treating various medical conditions in which intestinal transit is compromised.
  • the present invention refers to a sphincter-type intestinal valve for voluntarily regulating intestinal transit, with or without intestinal stomata, which comprises a biocompatible tubular intestinal casing having an adjustable biocompatible electromagnetic valve arranged in said casing; a mechanical intestinal valve arranged at a free end of said biocompatible tubular intestinal casing; a check valve arranged at a free end of said mechanical intestinal valve, which is coupled with the free end of the mechanical intestinal valve, and where the free end of the check valve is in contact with the outside; and a sealed rotary occluder that seals the free end of the check valve.
  • FIG. 1 is a side view of the assembly of the sphincter-type intestinal valve in an intestinal segment in its final position.
  • FIG. 2 is a side view of the biocompatible tubular intestinal casing.
  • FIG. 3 is a perspective view of the adjustable biocompatible electromagnetic valve.
  • FIG. 4 is a perspective view of the mechanical valve.
  • FIG. 5 is a view of the check valve and the sealing occluder.
  • FIG. 6 is an external, panoramic view of the rechargeable external device.
  • FIGS. 1 to 6 The following description refers to FIGS. 1 to 6 interchangeably.
  • the sphincter-type intestinal valve ( 1 ) referred to in this invention allows for voluntary regulation of intestinal transit in any segment of the small intestine or colon according to the specific needs of the surgeon or patient, either with or without an intestinal stoma, which can be used in two different embodiments: first, as an artificial sphincter of an intestinal stoma, and second, as an electromagnetic intestinal containment valve in the absence of a stoma.
  • the biocompatible tubular intestinal casing ( 10 ) comprises a thin film made of a biocompatible material, which can cover a specific intestinal segment of various lengths, and allows the adjustable biocompatible electromagnetic valve ( 20 ) to be attached to its structure and to the intestinal wall, while also protecting the intestinal segment used.
  • Said structure consists of a barium thread ( 12 ) arranged circumferentially at the ends and halfway along the length thereof, allowing said structure to be identified along the entire length thereof, as well as biocompatible support bearings ( 13 ) arranged cardinally around the edges of the ends allowing attachment either to the intestinal serosa or to other anatomical or valvular structures, accordingly.
  • the biocompatible adjustable electromagnetic valve ( 20 ) is mainly made up of a biocompatible support structure ( 21 ) which can be attached directly either to the intestine or to the biocompatible tubular intestinal casing ( 10 ).
  • Two electromagnets are provided inside the biocompatible support structure: one with positive polarity ( 22 ) and the other with negative polarity ( 23 ), arranged one in front of the other and providing direct compression when activated, thus collapsing the intestinal lumen of the segment being used.
  • the valve is secured in any position by the holes ( 24 ) that allow the surgeon to suture it at the appropriate point.
  • the electromagnets have an individual internal cable that connects to the cable of the opposite-pole magnet through the inside of the biocompatible support structure, and together they constitute the biocompatible support cable ( 25 ) which connects both polarities.
  • the biocompatible cable is exteriorized during the surgical procedure by a counter-opening through the abdominal wall to connect to the rechargeable external device ( 50 ), which supplies electrical power to activate the electromagnets.
  • the rechargeable external device ( 50 ) is a device that generates an electrical signal that activates the magnets ( 22 , 23 ), which in turn allow intestinal closure by attracting one another. Said activation signal is transmitted either through the biocompatible cable ( 25 ) or wirelessly, generating the activation signal within a distance range close to the patient.
  • the device may be rechargeable by a conventional external power cable ( 51 ) plugged into an electrical outlet ( 52 ) or by using batteries.
  • the mechanical intestinal valve ( 30 ) is selected from the group of on/off valves, so that the mechanical valve has only two positions: a first position allowing the passage of fluid therethrough, and a second position preventing the passage of fluid therethrough.
  • the mechanical intestinal valve ( 30 ) is made up of a rigid cylindrical structure ( 31 ) made of a biocompatible material, which allows the mechanical sealing of the intestinal lumen ( 32 ). This valve is able to extend its length in accordance with the overall thickness of the abdominal wall ( 100 ) by integrating the biocompatible intestinal structure ( 10 ).
  • the attachment of the elements that make up the valve to the entire abdominal wall from the innermost layer (peritoneum) to the outermost layer (skin) is carried out via two main mechanisms: first, by the inflammatory reaction which generates scar tissue (fibrosis) and seals the spaces between the devices and the abdominal wall; second, through the biocompatible bearings ( 13 ) and the holes ( 35 ) in the inner ( 33 ) and outer clamps (not shown), stabilizing the device on the structures as required through the use of absorbable suture material.
  • the mechanical intestinal valve ( 30 ) is also activated via two mechanisms activated manually by either the patient or another person.
  • the first mechanism activates two lateral symmetrical resistances ( 36 ) which collapse the intestinal lumen due to the extrinsic compression of the intestine, thus closing the intestinal lumen ( 32 ).
  • the second closing mechanism is performed by a check valve ( 40 ).
  • a sealing occluder ( 41 ) closes, it pushes a circumferential metal resistance ( 42 ) that prevents the gradual passage of stool.
  • the check valve ( 40 ) is deactivated, allowing the decompression of the circumferential metal resistor ( 42 ), which then returns to its initial position, allowing the flow.
  • Said valve ( 40 ) has circular clamps ( 43 , 44 ) on its outer and inner edges, which allow the device to be attached to an anatomical structure or to parts of the device.
  • the inner clamp ( 44 ) it allows attachment either to the abdominal wall components ( 100 ) or to the biocompatible tubular structure ( 10 ), so as to achieve the extension required for very obese patients.
  • the outer clamp ( 43 ) it is in contact with the skin, allowing cutaneous attachment, as well as the adaptation of accessories for draining or cleaning the stoma and the sealed rotary occluder ( 41 ).
